Introduction
Postoperative adhesions are one of the most common complications following abdominal, pelvic, and gynecological surgeries. Clinical studies report adhesion incidence rates ranging from 67% to 93% after general abdominal surgery, and up to 97% after open gynecologic pelvic procedures (Liakakos et al., 2001). These abnormal fibrous bonds between tissues can lead to chronic pain, intestinal obstruction, infertility, and increased surgical complexity in future operations.
To address this challenge, medical professionals increasingly rely on adhesion barrier gel as a physical intervention that separates healing tissues during the critical postoperative window. Among various materials, sodium hyaluronate gel has emerged as a preferred choice due to its natural origin, excellent biocompatibility, and optimized degradation profile.
Singclean® Medical Sodium Hyaluronate Gel for Anti-adhesion, a patented absorbable adhesion barrier gel, is one notable product that has obtained regulatory certifications in 37 countries, including the United Kingdom, European Union member states, Thailand, Vietnam, and Peru.
What Are Postoperative Adhesions and Why Do They Matter?
Adhesions form when the body's natural healing response to surgical trauma leads to fibrin deposition, inflammatory cell infiltration, and ultimately, permanent fibrous connections between adjacent tissues or organs that should remain separate.
Pathophysiology of Adhesion Formation
The process begins immediately after surgery:
Tissue trauma increases vascular permeability
Inflammatory response triggers fibrin precipitation
Decreased fibrinolytic activity allows fibrin to persist
Fibroblast invasion and collagen deposition create permanent adhesions
Neovascularization stabilizes the adhesive tissue
Common Locations and Complications
Adhesions most frequently occur in:
Abdominal cavity: intestines, liver, stomach, reproductive organs
Pelvic region: uterus, fallopian tubes, ovaries
Tendons, joints, and spinal nerves
Asherman syndrome (intrauterine adhesions) is a recognized cause of infertility. Small bowel obstruction (SBO) , another serious complication, accounts for approximately 300,000–350,000 hospitalizations annually in the United States, with an estimated 30,000 deaths. Retrospective studies suggest that 65–75% of SBO cases are caused by adhesive disease (Reddy & Cappell, 2017; Ray et al., 1998).
How Adhesion Barrier Gels Work
Understanding the mechanism of adhesion barrier gel is essential for clinicians selecting postoperative care protocols. These materials function through several complementary pathways.
1. Physical Separation During Critical Healing Window
Adhesion formation begins within hours of surgery and continues actively through postoperative day 7. No new adhesion formation occurs after day 7 (Davey & Maher, 2007). Therefore, optimal prevention requires intervention throughout this 7-day critical period of peritoneal healing (Gonzalez-Quintero & Cruz-Pachano, 2009).
Sodium hyaluronate gel-such as Singclean®-forms a spatial sieve-like network structure when applied to tissue surfaces. This biomechanical barrier physically separates adjacent organs and surgical sites, preventing fibrin bridges from forming during the most vulnerable healing phase.
2. Lubricating Properties
The viscoelastic nature of sodium hyaluronate gel reduces friction between moving tissues during healing. In abdominal and pelvic cavities, where organs constantly shift with patient movement and peristalsis, this lubrication minimizes mechanical disruption of healing wound surfaces.
3. Biocompatibility and Safety
Hyaluronic acid (HA) is a linear natural polymeric mucopolysaccharide composed of repeating units of β1,4-linked D-glucuronic acid and β1,3-linked N-acetyl-D-glucosamine. As an endogenous substance found throughout the human body, HA demonstrates:
No species difference or immunogenicity
Non-toxic profile
Complete biodegradation through enzymatic activity (hyaluronidase)
Excellent tissue adhesion
Because HA is naturally present in human connective tissue, there is no autoimmune rejection or adverse immune response.
4. Optimized Degradation Time
Exogenous HA is first degraded in lymph nodes and the liver under the action of hyaluronidase. After partial degradation, it enters the bloodstream, breaks down into monosaccharides, enters cellular metabolism, and is finally excreted from the body.
Critically, degradation of HA beyond 7 days can endanger peritoneal wound healing. Singclean® is specifically formulated to maintain barrier function for approximately 7 days, then completely clear-aligning precisely with the adhesion formation window without impairing normal healing.
5. Promotion of Fibrinolysis and Wound Healing
Beyond physical separation, HA actively promotes physiological repair by:
Enhancing phagocytosis of macrophages, reducing scar formation
Absorbing swelling and compressing bleeding points to reduce exudation
Stimulating mesothelial cell proliferation
Common Clinical Applications of Sodium Hyaluronate Anti-adhesion Gel
The versatility of sodium hyaluronate gel allows application across multiple surgical specialties. Below are the most common clinical scenarios supported by established protocols.
Obstetric and Gynecologic Surgeries
| Procedure | Application Method | Recommended Volume |
|---|---|---|
| Cesarean section | Apply to uterine incision surface, bladder reflection, and medial aspect of rectus abdominis muscle | 5 ml |
| Hysteroscopic surgery (polyps, myoma enucleation, uterine septum, adhesion separation) | Inject into uterine cavity postoperatively | 2–3 ml |
| Ovarian cyst excision, endometriosis excision | Apply to peritoneum and pelvic area before abdominal closure | 5–20 ml |
| Fallopian tube recanalization | Inject into fallopian tube after lavage | 2 ml |
General Abdominal Surgery
For abdominal operations including hepatobiliary, pancreatic, splenic, gastrointestinal, and hernia surgeries, clinicians apply 5–20 ml of medical sodium hyaluronate gel to the peritoneum and pelvic area before closing the abdomen.
Clinical Evidence Supporting Use
Academic literature demonstrates the efficacy of adhesion barrier gel containing hyaluronic acid:
A meta-analysis by Zheng Fei, Xin Xin, He Fei, et al. (2020) published in the European Journal of Obstetrics & Gynecology and Reproductive Biology found that hyaluronic acid gel significantly reduced the incidence of moderate and severe intrauterine adhesions and significantly improved pregnancy rates after miscarriage.
Wen-Ling Le, Chia-Hao Liu, Min Cheng, et al. (2021) in the International Journal of Molecular Sciences reviewed multiple systematic reviews and meta-analyses, concluding that HA not only demonstrates lower incidence but also reduced severity of intrauterine adhesions in HA-treated patients.
Singclean® Clinical Trial Data
A clinical trial enrolling 307 patients (161 obstetrics/gynecology cases, 146 general surgery cases including hepatobiliary, gastrointestinal, and hernia surgery) evaluated the effectiveness of Singclean® Medical Sodium Hyaluronate Gel for Anti-adhesion.
Patient demographics: Mean age 38.33 ± 12.90 years; 67 males, 240 females
Primary endpoint: Incidence of adhesion events or infertility within 12 months post-surgery
B-ultrasound results at 3 months: Significant reduction in intrauterine adhesions (IUA) after induced abortion, with particularly notable reduction in moderate and severe IUA
Hysteroscopy confirmation: Evaluated according to the 2015 "Expert Consensus on the Diagnosis and Management of Intrauterine Adhesions in China" issued by the Chinese Obstetricians and Gynecologists Association
Conclusion from clinical findings: Singclean® effectively inhibits fibrin deposition and condensation, forms a physical barrier protecting wound surfaces from friction, remains in the body for approximately 7 days, and demonstrates a low incidence of adverse events.
